I needed a solution without sessions or cookies, the public place
wasn't the problem - I used encryption for that. The problem was the
replayability but I fixed that as well by making sure a captcha can
only be used once (by utting it into a unique index column with the
comments). Anyway - thats completely offtopic. I just told the story as
an example of a "clever spammer".
